HAT-BRIM-WIRING MACHINE.

Specification of Letters Patent.

Patented Oct. 3, 1911.

Application filed July 18, 1910. Serial No. 572,556.

To all whom it may concern:

Be it known that I, ALBERT HAWORTH, a subject of the King of Great Britain, and a resident of Luton, England, whose postoflice address is 39 Brook street, Luton, Bedfordshire, England have invented a Hat- Brim-VViring Machine, of which the following is a specification.

This invention relates to a machine for binding the flat or curled edges of hats or other articles composed of soft non-metallic material.

In my machine there is comprised a device for positioning the stiffener relatively to the edge of the hat brim, and for gathering up the overlapping portion of the material and gradually turning it over until it is wrapped around the stifiener; this device will hereinafter be referred to as a doubler. There is also comprised a rolling disk or equivalent means for securely tucking in the end of the turned over material between the wire and adjacent face of the brim; a further disk or equivalent for assisting the action of the first one; and improvements in the driving and feed mechanism as detailed hereinafter. v

A preferred form of my invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation, and Fig. 2 a plan view of my machine, and Figs. 8, 4 and 5 illustrate the doubler on an enlarged scale.

The material 1 on the face 2 of the hat brim 3 overlaps the latter by a portion 4; the stifi ener consists of a length of wire 5 and it is required to guide this wire stiffener to the verge of the other face 6 of the brim 3, to wrap the portion 4 of material around this stiffener and then to press it well home between the face 6 and the stiffener 5. The doubler to carry out the first two steps comprises a helical guide strip 7 and a wall 8. At its forward end 9 the strip is vertical and forms a continuation of the walls face, but toward the rear it curls overgradually at first but more decidedly later-until at its rear end 10 it has turned through about 180, and forms a tubular guide that encircles the stifiener already wrapped around with material as hereinafter described. The doubler is suspended by an arm 14:, supported by a clip on lug 12 of frame 13.

The periphery of the rolling disk 15 is tapered concavely from top to near the bottom, where the disk is widest, a somewhat sharp-edged ridge 16 being formed preferably by slightly beveling its bottom surface as shown. The periphery of the adjacent disk 17 is tapered inversely to disk 15, and the bottom of said disk is slightly lower than that of disk 15. The opening left between the two disks corresponds more or less to the shape of the covered stiffener.

The disk spindles have bearings in brackets 18, 19 in the frame and are rotated in mutually opposite directions by suitable mechanism such as that afterward described. The wheel 15 is so mounted that it can be moved toward or away from wheel 17, being kept pressed toward the latter under the influence of a spring or equivalent.

20 is an idle wheel.

When starting operations, the stifiener 5 with material in position for being wrapped around is caused to engage with the part 10 of the guide strip 7. The latter and the wall 8 acting jointly serve to keep the stiffener 5 at the edge of the rim 3; which is introduced between the bottom of the disk 15 and the idle wheel 20 which supports it, and it is dragged or fed forward by the rotation of the disks. As this takes place, the overlapping portion 4 of the material first engages with the wall and strip at 9 and is bent into an upright position; it is then gradually turned over as already described and finally pressed right home by the edge 16 as the stiffener 5 covered by material passes through the space between the disks 15, 17 I do not wish it to be understood that the doubler is absolutely indispensable, as the disks can be advantageously used without it as compared with the previously known method of producing the desired result by hand.

Any suitable method may be employed to rotate the disks. That shown is preferred, and allows the disk 15 to be moved closer toward or farther away from disk 17 so as to be adjustable for different sized brims, or for any irregularity in the work being operated upon.

The cogwheels 21 and 22, which are secured on the spindles carrying disks 15 and 17 respectively, do'not engage with one another, but with intermediate wheels 23, 24, respectively which transmit the drive imparted by the worm and worm wheels 25, 26, driven from the pulleys 27 which are rotated either by hand or by power. The bracket 18 carrying the disk 15 is itself carried by a forked rod 28, passing through guides 29 in the bracket 19; the stem 30 of this forked rod passes through the head 31 of the frame and is slotted to receive the lever 32 passing transversely through a slot 33 in said head and pivoted therein at 34. By actuating said lever 32 the rod 28 can be moved to and fro, and the disk 15 thus made to approach and recede from disk 17. A spring 11 surrounding the exposed part of rod 30 and bearing against the head 31 at one end and the knurled knob 35 at the other, serves to keep the disks as close together as the thickness of material will al low. The tension of the spring can be regulated by screwing or unscrewing the knob 35 which is screw threaded, and engages with a threaded portion of the stem 30. The slot 33 has a downward extension 36 in which the lever 32 can be held when it is required to retain the disk 15 in a position apart from disk 17. Obviously instead of the lever and slot arrangement for moving the rod 30 an eccentric device or other means could be substituted.

In order that the wheels 21 and 23, 23 and 24, 24 and 22 may engage with each other at all times, whether the disks 15 and 17 be in contact or separate, I so mount them that wheel 21 can move radially around wheel 23 and wheel 23 similarly around 24 when the rod 28 is slid one way or the other. To do this wheel 23 is carried by two links 37, 38 whose other ends are respectively mounted on the spindles of wheels 21 and 24 or on collars on the wheels themselves; the wheel 24 is carried by a bracket that forms an extension of the bracket 39 carrying wheel 22. Instead of the extension bracket a link, similar to the others, may be used. Of course, this arrangement is not essential to my invention, as wheels 21 and 22 could be made to interengage directly with one another, and to be separable when the rod 28 is moved; or the link between wheels 23 and 24 could be dispensed with, in which case the wheel 21 would be caused to swing in a curvilinear path, as distinguished from the' rectilinear pat-h in the preferred form.

The idle wheel 20 can be moved toward or away from the disks 15, 17; it is mounted on a collar of the tubular spindle 40, and a pin, 41 with head 42 at one end and thread ed at its other end to engage a fly nut 43, passes through said spindle. On said pin 41, there is a collar 44 too large to pass through the hollow spindle, and this engages with the slot 45 in the frame. The fly nut 43 bears against the end of spindle 40 and not against wheel 20; by screwing it up tightly the spindle and pin can be clamped against sides of slot 45, when the wheel 20 is at required distance from wheels 15 and 17.

By the aid. of washers strung on the pin 41, against the collar 44, the wheel 20 can obviously also be adjusted sidewise.

The bearing 46 for the spindle of worm 25 is mounted on or forms part of a slide 47 which" can slide on the head 31 and be clamped in the required position by nuts 48.

The whole of the working parts may be inclosed in a light metal case (shown by dot and dash lines 49) which may be mounted on a box section stand.

It will be clear from the foregoing that my invention is designed and intended to operate upon any kind of soft non-metallic material and that it essentially consists in a single pair of coacting members for binding such material, in contradistinction to devices in unrelated arts which are dependent upon a series of pairs of coacting devices which successively act to bind or roll material.

I claim:

1. In a machine for binding the brim edges of hats or like soft non-metallic material, the combination with a single pair of disks, one of which is provided with a tapering periphery and a flange projecting therefrom and the other of which has a like peripheral contour for binding the material interposed therebetween, and means supporting the body of the brim or material in parallel relation with one of the side faces of said disks throughout the binding operation.
